The drawings show the inventionA embodied in a gasrange, but it will beunderelements, for example the lectric heating elements, may besubstituted for the gasburners, if desired.

In the construction illustrated, A designates the base-.frame of therange supported an oven unit comon legs A Bl designates grising a bakingoven B and a broiling oven 2; and C designates the cooking-top of which,in the illustration given, has :a closed central top section C whichsurmounts the heating unit C2 which is mounted on the base A; `Theheating section C2 is equipped with a ,burner-box Cs which communicatesthrough lues C4 and Cs with a supplemental air heater C, as shown inperspective in Fig. 6. p

The oven unit B preferably is mounted on one end of the base-frame A, inany suitable `manner. The'cooking-top C extends laterally froml the ovenunit posed 'opposite the lower portion of the main oven. The cooking-topcomprises a perimetric frame 1 having a depressed pory tion C2. referredfrom,

B, but is distion, .or rabbet, 1a on which the end portions ofthecentral plate C are supported. `'The frame C is supported at a suitable`distance above the base-frame A, in anyy suitable manner. Flanking thecentral plate C are be the grid-plates l2 and 3 which are disposed abovethe burner-boxes 2 and 3, which flank. the upper-portion of the heatingsec' Extending across the front vof the range is the gas-manifold 4,whichsupplies pipes leading to the burners 5' located in theburner-boxes 2EL and 3. The `pipes which supply said burners arecontrolledlb means of valvesA 6. The cooking sections which flank theheating section may be of any desired construction. In the constructionillustrted, the range is. rovided between the heating section and t evbroiler-oven with a 'space 7 which may serve as ,a ywarming chamber. Also, at the opposite side of the heating sectlon C2, thel rangeisequipped with a triangl'l ar plate 8 which serves both vas anish'plate and a brace. l

The rear wall 9 of the range extends above the cookin s ace 10 and is eui ed with a shelf lLg p 7' q pp f The heating section erably comprisinga front frame v12 having its lower ends secured' bybolts '12n tothe C2of the range prefi base-frame A andV having its upper end secured, inany suitable manner. to the perlmetri'c frame 1 of the cooking-top; adoor 13 mounted on the frame 12; the burnerbox Cs having its lower wallssecured by f bolts 14 to theframefA; a gas-burner 15 mount-ed in thelower portionof the burnerbox C3 and supplied with gas throughy a pipe15? which communicates with the manifold 4 and which is controlled; by avalve 15"; the' forwardly and upwardly inclined flue C* whose rear endcommunicates through a passage 16 with therear upper portion of theburner-box C3; ue C5 with which lthe upper'front end/of tle flue C?communicates through a passage As most clearly shown burner-box C, andthe lues leading t erements and the walls-of the chamber D. The' and thetop` in Fig. 5 the f 105 are located ina chamber D which compriseswalls` extending from the baseilues 17 are also cross connected byairwith uues'17 and 17?, afforded by the spaces between the elementsmentioned.

The top flue C has its upper'wall cut away throughout the greater partof the length of the flue, as indicated at18; and the central plate C',forming the closed top of the central section, serves as a top wall forthe ue C".

The supplemental heater C6 is disposed back of the rear wall 9. It is ofrectangularzform land is disposed parallel with the back of the range.Preferably, it com rises .an enlarged gas- Hue 19, and a pair o airflues'20 and 21 located respectively in front of and behind the gas-flue 19.

Theupper gas-flue C*s of the central heating sectlon extends through the,rear wall 9 of the Arange and through the front airflue 20 as indicatedat 22, and communicates the lower portion of the enlarged gaslue; 19 ofthe su plemental heater. vThe air-flue's 17, 17 andi17b of the centralheating sections C communicate `through la passage 23 with the lowerportion of the air-Hue 20 ofthe supplemental heater. The

- air-Hue 20 opens through a passage 24 at itsv upper end andthuscommunicates with the external atmosphere at theupper rear portion ofthe ran e andk in the rear of the usual back wal f of the range. The airassage 21 is open at both the upper and ower ends. Its function is` toprovide for independent air circulation which willheat i i the air onlymoderately so that the extreme 35 rear' wall 25 of the supplementalheater will not become hot. Thus, this wall `may safely be laced veryclose to the wall ofthe room.

l e lower portion ofthe door 13 is shown ywith-an air register 26through which air may be admitted to lthe burner 15. Also, it ispreferred to vprovide the bottom Vwall 27 of the burner-box C withperforations 27 for admitting air to the burner 15.. The burner 15 isshown .equipped with supporting lugs 28 which rest upon the lbottom wall27. In the illustration given, a water-coil 29 is shown mounted in thebox C3 above the burner 15. This coil may be connected with a lhot watertank, in any suitable manner.

The feature may be used, lor. omitted, as desired. n f

`In my reissue Patent'No. 15,850, granted May 2,7, 1924 there isshownand described a rangejhaving an oven unit anda cookingthe top,theseI parts being Yinterchangeably mounted upon a suitable base-frame.y In the resent invention, use may be made of ieature ofinterchangeability, ifdesired. Also, while I have illustrated theinvention as embodied in a range wherein the central section of thecooking-top comprisesthe top of a-heating unit, it will ybe-understoodthat the arrangement may be modified in any desired manner.

By reference to Fig. 5, it will be noaay desire that air is supplied tothe `air-flue 17 by .ing the supplemental heater C?. However,

the supplemental heater may be` omitted, if y rIlhe supplemental heateris su portedl onthe rear end of thel gas-flue (il,

and is'y also connected with the air-flue 23.

Thesupplemental heater may be additionally lconnected with the back wallof the range, as by means of screws 32, which pass through erforations32awith which a l flange yo provided. l The as-fiue 19 ofthesupplemental heater prefera ly is, rovided with baiilevplates 33, 34.-and 35, W ich are staggered' with relation to each other and arranged in'any desired manner to compel the gases to pursue a circuitous route.Extending laterally from the upper ortion of the gas-flue 19, is agas-flue 36. Fhis Hue V36 extends back of the upper portion of the'ovenand is provided with an ingress opening 36 with which communicates aflue 37 which conducts .the gases from the oven to the flue 36, asappears from Fig. The flue 36 'is'proythe supplemental heater. is

vided with a nipple 36b for connection with a stove pipe.

It will be understood that when the heat section is in use, the top'plate 'C' ywill become suiiiciently heated to serve -rfor cookingpurposes. The plate C is shown equipped with removable leads 38. The endportions of the plate C are connected'by screws 39 with the marginalframe C; and the edge Aunderstood that the improved constructionprovides a range-section whose top forms a part of the cookin top oftherange. AThis section can be us both for heating purposes and for cookingand warming purposes. The arrangement illustrated, wherev1n the heatingsection of the cooking-top portion of the range isv spacedgfrom the ovenasuicient distance to provide an interposed warming chamber 7, ispreferred. Y

While it is preferred to space the top of the burner-box C some distancebelowv the` bottom wall of the flue C and employ the inclined Hue C* toconnect the rear portion of the burner-box with the front portion..

of the flue C, it will be understood that this construction may bemodified, as desired.

The foregoing `detailed `description has been given for clearness-ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, but theappended claims should be Vconstrued as broadly aspermissible, in view Aof the prior art.'
